Don't assume you can catch up on or stock up on sleep at the weekend and always feel better.

"Even one night of disturbed sleep can impact on mental and physical performance the following day," said Dr Henderson.

He further added, "It is however possible to catch up but can take days or even weeks for the body to return to a normal pattern. If trying to make up for lost time, go to bed early and wake up at a normal time instead of sleeping in late."

4) Don't ignore night sweats

For those who suffer from night sweats it can be difficult to establish whether you have woken because you are sweating, or you woke and then started to sweat.

"If the sweat wakes you up then you are having a menopausal night sweat and should look into ways of reducing this, such as eating healthy foods little and often," revealed Dr Marilyn Glenville, author of The Natural Health Bible for Women.

She further added, "However, if you wake and then you start to sweat or get other symptoms like palpitations, or just feel wide awake, then this is most likely caused by an adrenaline surge because your blood sugar has dropped during the night."

She explained it is possible to reduce this by keeping blood sugar balanced during the day, and having a slice of brown toast or another carby snack before bed.

"One way you can help do this is by having a small snack of complex carbohydrates, such as an oat cake, half a slice of wheat or rye bread, about an hour before bed. This will stop your blood sugar dropping overnight, and prevent adrenaline from being released into your bloodstream and causing you to wake," she suggested.
